The U.S. Nuclear Regulatory Commission (NRC) proposes to amend its regulations that govern the licensing of uranium mills and the disposition of tailings and waste that arise from the extraction and milling of uranium by issuing risk-informed requirements for groundwater protection at uranium in situ recovery (ISR) facilities. The NRC's current regulations are focused on conventional uranium milling and do not expressly address uranium extraction by the ISR process. Additionally, NRC proposes to amend its regulations that govern decommissioning timeliness for all licensees to provide additional flexibility for licensees to delay the initiation of decommissioning activities in situations where safety would not be impacted.

The U.S. Nuclear Regulatory Commission (NRC) has issued a one- time exemption to Southern Nuclear Operating Company (SNC), authorizing Vogtle Electric Generating Plant Units 1 and 2 (Vogtle 1 and 2) to retain a single Neutron Source Assembly (NSA) in its current storage cell within a multi-purpose canister ((MPC-32), serial number MPC-707) at the Vogtle Independent Spent Fuel Storage Installation, in a manner that is inconsistent with the loading restrictions specified in Certificate of Compliance (CoC) No. 1014, Amendment 11, for the HI- STORM 100S Version B dry storage system. The exemption allows the NSA to remain in a peripheral basket cell, contrary to Appendix B, Table 2.1-1, which restricts NSA containing assemblies to designated interior cells. The NRC's determination is based on SNC's safety evaluation and supporting analyses demonstrating that the configuration continues to meet applicable safety requirements for criticality control, shielding, thermal performance, structural integrity, and confinement.
